Quick release levers
Quick release levers hold wheels and seat in
position.
A quick release lever consists of two basic
parts: the lever on one side provides the
clamping force.With the adjusting nut on the
other side you adjust the clamping tension on
the screw thread.
To open the quick release, move the lever
away from the frame. In doing so the inscrip-
tion "open" should be visible on the lever.
To close the quick release, move the lever with
power in the other direction so that the word
"close" is visible on the outward side of the
lever.At the start of the lever's motion, for, say,
half of its movement, the lever should move
very easily, without any clamping action.
In the second half of the lever's movement the
force on the leer should increase considerably,
corresponding in the end to 15-20 kg (46 lbs).
In its final position the lever should lie parallel
with the bicycle and should not stick out to
one side.
Check the security of the lever by attempting
to twist the lever. If the lever can be made to
pivot around in a circle the clamping is too
loose.You must re-open the quick release,
hold the lever and increase the clamping ten-
sion. Do this by screwing the adjustment nut
on the other side by half a turn. Close the
lever and check the clamping anew.
Finally, check that the part being secured is
firmly fixed: Lift each wheel several inches off
the ground and give it a slap onto the tire
from above.A properly fixed wheel will remain
secure in the frame's dropouts.
The dropouts of the fork of your
GrassHopper are designed as safety dropouts.
Therefore you always have to loosen the
clamping nut of the quick release when you
take off the front wheel.When you reassemble
it do not forget to tighten the nut again!
Parts that are fastened with a quick release
open easily.Thus, they are more susceptible to
theft.Therefore, always secure the wheels with
a lock when you park your bicycle. It is also
possible to exchange the quick releases with
special security screws (e.g. from P
ITLOCK
or
K
RYPTONITE
) that can only be opened with a
special tool. For this please consult your local
specialist dealer.

Caution!
Always carry your bicycle over
stairs and curb stones. Do not ride through
big road holes. Especially when road holes
are filled with water it is very difficult to
guess how deep they really are. In case you
hit such an obstacle frame and fork may be
damaged which can result in a serious fall.At
first, the damage may be unnoticed. Please
check your bicycle immediately for deforma-
tions and cracks. If you are in doubt please
consult your local dealer.
Danger!
An incompletely or improperly
closed quick release can result in parts com-
ing loose, and hence in a crash, possibly re-
sulting in serious injury.
